Effects of device portabilityPower consumption limited computing power, low quality displays, small disks due tolimited battery capacity CPU: power consumption ~ CV 2 fLoss of data C: internal capacity, reduced by integration V: supply voltage, can be reduced to a certain limit f: clock frequency, can be reduced temporally higher probability, has to be included in advance into the design(e.g., defects, theft)Limited user interfaces compromise between size of fingers and portability integration of character/voice recognition, abstract symbolsLimited memory limited value of mass memories with moving parts flash-memory or ? as alternativeDr.-Ing.
